Monitoring Script

[dvknn]

Hi,

How can I grep for the last line in a file?

the last line in my file will (always be) be

'Server is DOWN'.

I need to grep for this, and if the last line is ... 'Server is DOWN', then I need to send a mail.

How can I do that?

Thanks,

You can use
tail -1 yourfile

hope it helps.

Thanks.

My script is like this:

#!/usr/bin/ksh
grep 'UserProfileServer is DOWN' appcheck.log > appcheck.err

if (-s appcheck.err) then
MSG='Server is DOWN'
mail abc@yahoo.com < $MSG
fi

I am getting an error &quot;upsCheck[8]: -s: not found&quot;

What is it that I am doing wrong here?

thanks,

I believe you are using korn shell.

The 'if' syntax for korn shell,

if [ -s appcheck.err ]
then
MSG='Server is DOWN'
mail abc@yahoo.com < $MSG
fi

Hope it helps.

OK...that's not working..

I have a file which has 'Server is DOWN' line in it. I have to grep for this line and then sned an email.

How can I do that?

Thanks,

There may be some other simple way.. but you can try this too if its OK for you..

#!/bin/sh

check=`grep -i server ./yourfile | tail -1`

if [ check -eq 'Server is DOWN' ]
then
mail dvknn < letter
fi
